190 ASPLEXUM. 



Hal). Tsus Sima, an island in tlie Gnlf of Corea, IVilford, n. 717.— I name this 

 fine and most distinct species, quite nnlike any known to ine, in compliment to 

 JdIim Ward, Esq., R.N., Commander of 11. M.S. Acta'on, who, during a surveying 

 voyage in the north Chinese and Japan seas, gave our hotanical collector, Mr. 

 M'iltord, every facility and assistance that could he desired in herhorizing on 

 shore: the result has been a very interesting herbarium from countries never 

 before visited by the botanist, and among them some very interesting Ferns. The 

 habit of the jiresent species is more that of an Aspidioid Fern than an J.ijjlenium : 

 so much so, that hut for the very distinct, though young sori, 1 should have re- 

 ferred it to the group of Lastrea among Aspidiece.

Hab. Warmer parts of Europe, especially Greece, Spain, Portugal, islands of 

 the Mediterranean, extending north to the southern parts of Great Britain. Al- 

 geria, Madeira, Azores ; St. Helena, /. D. Hook, in Herb. Nosh: — Avery distinct 

 species, reaching its northern limit in the southern districts of the FBritish Isles. 

 Of this species the A. obovatum, Viviani, is a very trifling variety. My var. 

 elpffam, from Hongkong, 1 now consider a truly distinct species, the next to bfi 

 described.

 brown scales, stipites tufted short 1-2-3 inches slender

 bright green much attenuated below 4 inches to a span long 

 bipinnate, below simply jnnnate with remote dwarfed flabel- 

 late or reniform pinnfc, the rest of the pinnae \-'i of an inch
